Grafana
1

Hello,

I’ve an issue to enable ssl on grafana (docker container)

detail :
OS : centos 7
docker version : Docker version 19.03.7, build 7141c199a2

the error :
2020/07/30 09:46:36 http: TLS handshake error from x.x.x.x:yyyy remote error: tls: unknown certificate authority

my historiy command :

`openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out server.csr`

I retrieve the crt file to my certificate authority server
I put the root CA on the docker server : /etc/pki/ca-trust/source/anchors
then update-ca-certificate
in my docker compose :

    services:
      grafana:
    image: grafana/grafana:latest
    container_name: grafana
    ports:
        - "3020:3000"
    env_file:
        - 'conf/env.grafana'
    volumes:
        - /srv/grafana/ssl:/var/ssl```

and I have this issue.
I tryed this : 

https://localhost:3000/t/adding-a-custom-ca-root-chain-in-trusted-certificates-in-grafana-docker/18059 
it doesn't resolve my issue
